Frozen embryo transfer is the technique used in conjunction with IVF,  that allows cryopreserved/frozen embryos created in a prior stimulated IVF cycle to be thawed and transferred into a woman’s uterus.  

1. Baseline assessment
2. Hormone therapy (Estrogen and progesterone) and monitoring
3. Embryo transfer
4. Hormonal support and pregnancy test
5. Follow-up consultation

What is the survival rate of embryos?

Embryos are graded based on their quality before they are frozen. The best quality embryos are the ones who have the best chance of implantation and are the ones preferably chosen for transfer.  The survival of the embryos depends upon their prior quality, the resulting embryos surviving the freeze-thaw cycle. Usually embryo survival is close to 90-95%.

For how long can embryos be frozen?

Embryos can be technically frozen/cryopreserved for years. Their quality does not deteriorate over time.

What are the success rates following frozen embryo transfer?

Success depend on several factors such as the age of the woman, quality of the embryos frozen, the day of freezing (day 3 or 5), endometrial thickness. Success rates following frozen embryo transfer are as high as 60-70% per transfer.
